The SR-556 offers Ruger's legendary rugged reliability and employs a patent-pending, chrome-plated, two-stage piston-driven operating system that provides the user with a cleaner, cooler-running, reliable firearm that is truly state-of-the-art. The chrome-lined gas block and chrome-plated piston and regulator work together to provide a smooth power delivery stroke to the bolt carrier, and the by-products of the gas system are vented out the bottom of the gas block, away from the bolt carrier, keeping the action clean and free from contaminants.
